Chief Crown Prosecutor for Thames and Chiltern Crown Prosecution Service (CPS), Adrian Foster, believed that Johnson pulled the trigger but both he and Noble, from Kempton Avenue, played a “significant role in this planned attack”.

He continued: “They both acted jointly, together, and are clearly extremely ruthless, calculated and violent individuals.

“We know that nothing will bring Kerry back to her family and friends, but we hope that today’s convictions bring them at least a small sense that justice has been done.

“Our thoughts are very much with them all at this time.

“I would like to pay tribute to Kerry’s family and friends and the witnesses for their wholehearted support of the investigation and prosecution.”

Victim Kerry Reeves was gunned down in November last year

Speaking after the sentencing, senior investigating officer, detective chief inspector Mike Lynch, said: “The jury at Oxford Crown Court has found Charles Noble and Billy Johnson responsible for the murder of Kerry Reeves and today (May 31) they have been sentenced for this heinous crime.

"It is with regret that neither man showed any remorse for taking the life of an innocent woman by shooting her at point blank range.

“Kerry’s murder has had a huge impact on her family and the community of Abingdon.

“Although there can be no sense of happiness with the conviction of Charles Noble and Billy Johnson, I hope there is a sense of justice for Kerry’s mother, Nicky and her family.”
